In stamping automatic production line, no matter which section has trouble, the entire line will stop. The trimming section is especially easy to have various troubles. For example, scraps may accumulate around the tooling and cannot get into the scrap hole, or scraps stuck in tooling or guide chute, etc. The improper design of tooling may also cause wear and tear on press by scraps contacting press directly. In eta/DYNAFORM, through the simulation of scrap cutting and scrap shedding process, the above mentioned troubles can be effectively avoided and trimming tooling can be modified. This is an indispensable step in the tooling design stage.
Scrap Shedding Removal is an add on module which is utilized to simulate scrap shedding process. The whole process is completed on an integrated interface. The user does not have to provide any extra data except the practical process parameters such as motion curve, trim height, angle, practical mathematical modeling and material parameters, etc., which simplify the operations.
The typical Scrap Shedding Removal interface is illustrated in Figure 10.2.1, which includes the operation tool bar, tool definition interface, simulation setup interface and taskbar. The setup interface consists of four basic pages: SCRAP, VELOCITIES, TOOLS, and CONTROL.
